teatree will prevent lice
fleas will not infest humans they will bite you for a quick snack but will not live on you
lice if you get them take 70% rubbing alcahol, bun up the dreads pour it on (you dont got to soak em use plenty but dont got to drench the dreads its the fumes that kill) after u pour on a bunch wrap the bunned dreads in plastic wrap tuightly to seal in the fumes for a good 30 minutes
tips: the fumes may overwhelm you too so use a paper towel tube or a hose or tube to breathe tyhru to get fresh air from a foor or more away especialy if u got asthma or breathing issues, also..the alcahol wikl steralize the bite wounds but ..will sting like crazy so..scream yell punch the wall..but get through it u gotto leave it on long enough they can hold their breath 14 minutes so 30 minutes is a good guaranteed kill time
after washing it out pour on undluted acv soak 10 minutes and wash again this helps dissiolve the egg casing glue so they come off
most important
repeat these steps every 3 days..not 4 or 5 must be 3 for a min of 9 days
also adding neem seed oil to your shampoo u use to wash out the alcahol will help too
and in between treatments teatree oil will keep u sane when they are chewing on you apply it to your scalp they hate it so will not bite for sa couple hours when thery do start biting reapply

if your house is infested with fleas treat your pets or house or both no need to treat you only the house or pets
